Two 5kg granite blocks (can be obtained during the quest, with 45 mining)

A total of 52kg of sandstone (any combination will work as long as the number adds up to exactly 32kg and 20kg in separate sets; sandstone can be cut into smaller pieces if required. It's recommended to get 10 blocks of 5kg and one block of 2kg)
